Ramana Maharshi

If the mind is happy, not only the body but the whole world will be happy. So one must find out how to become happy oneself. Wanting to transform the world without discovering one's true self is like trying to cover the whole world with leather to avoid the pain of walking on stones and thorns. It is much simpler to wear shoes.

"Correcting oneself is correcting the whole world. The Sun is simply bright. It does not correct anyone. Because it shines, the whole world is full of light. Transforming yourself is a means of giving light to the whole world."

If a man considers that he is born, he cannot avoid the fear of death. Let him find out if he has been born or if the Self has any birth. He will discover that the Self always exists, that the body that is born resolves itself into thought and that the emergence of thought is the root of all mischief. Find from where thoughts emerge. Then you will be able to abide in the ever-present inmost Self and be free from the idea of birth or the fear of death.
